IMPROVEMENT In REGULATING cannon LUMBER-WAGONS.

TO ALL WHOM IT MAY CONCERN: H p

Be it known that I, JAMES W. DREW, of Stockhridge, in the county of Ingham, and State of Michigan,- have invented a new and useful Invention for Regulating Wagons; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the accompanying drawingspforming apart of this specificatiom in whichi Figure 1 is an invertedplan of my invention.

Figure 2 represents a sectional side elevation of thesame.

Similar lettersof reference in the two views indicate corresponding parts.

i The same parts described and shown in drawing, fig. 1, may be seen infig. 2, and'known by the same letters.

Theprincipal object of this invention is to destroy a certain motion given to our lumber-wagons .when on rough roads by'the striking of the front wheel against obstructions, such-as stones, ro0ts, logs, and blocks, andmany other obstacles which are more or less lying in their way.

The nature of iny invention, and its peculiar advantages, will be readily understood from the following description. V, 1 I

A represents a lumber-wagon, constructed after the common fashion, with the attachment of my invention for destroying that deadly hlow which our noble animal, the horse, is compelled to receive by the striking ofthe' tongue against his sides, sometimes with such violence as to break his legs, when crossing rough places.

This invention is called a regulator for wagons, because it entirely destroys the side motion'of the tongue F, which is caused by the striking of the front wheel against obstructions.

The regulator is very simple in construction, and also very efi'cctuah It consists of a simple wheel, B, suflicient in heft to operate as designed, z'. e., to not start easy when the wagon strikes an obstacle, and to hold itspositionuntil the wagon has passed over the obstacle, consequently keeping the wagon steady, and preventing the tongue from striking the team.

In order to apply this apparatus to a wagon to have this desired eflect, I will'furnish the wheel B with a small pinion, C, and attach them' securely together with one bolt, and-with the reach H'between th em.- Then I take the bar D, which is furnished on one edge with cogs, made to fit those of the pinion G, and put them together, as shown in fig. 1, and fasten the end of bar D. to sway-bar E securely with a bolt, as shown in the view, fig. 1. When this is done, it is'seen at once that the wagon cannot cramp or turn about, unless the wheel B revolves and lets the bar D move endwise over" the pinion C. I

Thefrent wheel of the wagon striking against an obstruction, hasthe same effect on the wheel B and bar D as when cramping but instead of a steady pressure, asin cramping, it is a blow, like that of a hammer,

which comes upon the wheel Ball at once, and before the wheel 13 has time to revolve and .let the front part oi the wagon (or one side of it) give way to the obstruction, the wagon is forcedover it, arid the wheel 13 remains perfectly still, and the horses escape that ugly blow of the tongue, which greatly annoys and fatigues them on rough roads. i y

This regulator is in the form of a balance-wheel, but it cannot be called a balance-wheel; Itoperates in no manner as a balance-wheel; it evens nomotion nor steadies any motion, but it destroys that motion entirely that has destroyed many of our horses, by bruisingthem up and breaking their legs with the end of the tongue of our common wagons. V i

All balance-wheels are applied to machinery to steady an uneven 'motion, and in order to do that theyv have to be put in motion; and some balance-wheels are geared up and run very fast and with great heft and force. This wheel 13 has no motion; it is always standing still when it is having an effect. The reason why it is made to turn at all, is simply to let 'the wagon turn around.

Having thus described my invention, what I'claim, and desire to'secure by Letters Patent, is-

1. The use and application of the wheel 13 to common team-wagons, for obviating the knock and jerk of the tongue or draught-pole F, on rough roads, as-substantially shown and described.

2. The bar D, pinion C, combined and operating in the manner as herein shown and described.
